5. Google Sign-In and Google user data

Signing in with Google is optional; you can also sign up with your email address or your device number. When you sign in with Google, BluCory receives only the following from your Google account (openid, email and profile scopes):

  • Your Google account ID
  • Your name
  • Your email address and whether Google has verified it

How we use it: only to create your account, recognise you and sign you in, and set the contact email of your account. We do not access Gmail, Drive, contacts, calendar or any other data in your Google account, and we never see your Google password.

How we store it: the Google account ID, name and email are stored with your account in our database (Oracle Cloud, Frankfurt), reached only over encrypted connections. We do not store Google access tokens; they are discarded once sign-in is complete.

Sharing: we do not share, sell or use data received from Google for advertising, and we do not send it to the AI service provider. It only resides with the infrastructure providers needed to run the service (server) listed above, or is disclosed to authorities where the law requires.

Removal and deletion: you can remove the Google link in the app under Settings > Account, and revoke BluCory’s access on the “Third-party access” page of your Google account. When you delete your account, the data received from Google is deleted too.

BluCory’s use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

6. Premium subscription through Google Play

In the Android app you can buy premium membership as a monthly or yearly subscription through Google Play. Payment is handled by Google Play; your card and bank details are never sent to us. To verify the subscription and follow renewals and cancellations, we receive from Google only the purchase token, the product and the subscription status. When you cancel premium in the app or delete your account, renewal of your Google Play subscription is stopped for future periods.

7. Cookies, data stored on your device and usage statistics

BluCory does not use advertising cookies or third-party trackers (Google Analytics, etc.).

  • Essential cookies: the cookie that keeps you signed in, the “remember me” cookie and the cookie that remembers the theme chosen on this device. The app cannot work without them; they do not require consent.
  • Preferences stored on your device: display preferences such as dark / light mode are kept only in your browser and are not sent to us.
  • Usage statistics: if you give explicit consent, we record which parts of the app are used and for how long, together with your account and a random device ID created in your browser. Nothing you type in fields (name, PIN, notes, email) is recorded. Results are reviewed only in aggregate, to improve the service. You can withdraw your consent at any time in Settings; this does not affect your use of the service.

8. Retention

We keep data only as long as the purpose requires, then delete, destroy or anonymize it.

DataRetention
Account details, measurement data, user contentWhile the account is open; deleted immediately when you delete the account; removed from backups within 30 days at the latest

You can delete your account yourself in the app under Settings > Account > Delete my account, or ask us to delete it at [email protected]. When you reset or transfer your device, the measurement data of that device is deleted; your account and aquarium records are kept.

9. Security

We take technical and organizational measures to protect your data against unauthorized access, loss and alteration.

  • All communication with the site and the app uses an encrypted connection (HTTPS).
  • Your PIN is never stored in plain form, only as a one-way hash.
  • Repeated failed sign-in attempts are limited; you are notified when your username or PIN changes or a device is reset.
  • The database and private configuration files are not reachable from the internet; only authorized persons can access the data.
  • If a data breach occurs, the Board and affected users are notified within the period set by law.
